Frozen Pork Roast In Instant Pot

Put a trivet into the middle of your pot with frozen pork roast on top. Sprinkle with salt and pepper and/or other seasonings you wish. Close lid and steam valve, push meat/stew button (or high pressure) for 55 – 60 minutes for 2.5-3 lbs. Allow pressure to release naturally when done.
  1. Add an additional 5 minutes per pound to the cook time.
  2. Realize that it may take a little extra time to come to pressure when cooking frozen meat.
  3. Be sure to natural release the pressure, and not quick release.

What does the meat setting on Instant Pot do?

It just defaults to high pressure for 35 minutes. You can then adjust the cook time for longer or less if you wish with the – or + buttons.

Frozen Pork Shoulder Roast Instant Pot

This is what you’re going to need to get out in order to get started:

  • Pork shoulder that is NOT defrosted is used for this recipe.
    1. If yours is not frozen then follow our Instant Pot pork shoulder recipe instead.
  • Olive oil is the best to use. I keep a container on my counter because it’s great for sauteeing all the things and for sauces.
  • Garlic is always in my fridge. I buy a large jar of minced to save me a ton of time, I rarely buy cloves that I have to dice myself.
  • Brown sugar will give this a sweet flavor you’ll love.
  • Balsamic vinegar gives our sauce a bold flavor. We use it in our beef arm roast recipe too. There are a ton of different types but this is my favorite, made by a local Idaho company. This one is a close second if you’re buying online.

  • Soy sauce goes on a lot of things in our house. Maybe it’s because I was born in HI but it’s my favorite thing to include in sauces and on rice.
  • Rosemary either fresh or jarred works. I rarely get fresh because we live in a very small town and produce is kinda’ lacking.
  • Broth is a much better cooking liquid than cups of water for sure. Beef is best because of this cut but vegetable would work too.
  • Cornstarch will thicken the gravy left in your pot at the end. Of course you can leave this out, or use flour instead but I like thick sauces!
  • This is a peek of it in the pot once it has cooked and steam has been released naturally. That step is important to keep it super moist.

    Let’s read a quick step by step on how this was done. There is a printable recipe card at the bottom of this post too though:

    Time needed: 1 hour and 45 minutes.

  • Prepare In a small bowl whisk together your minced garlic, brown sugar, balsamic, soy sauce, cornstarch and rosemary. If you wanted some heat you could add chili powder too. Rub your olive oil over the frozen cut of meat. Pour broth into pot. Place frozen roast in pressure cooker, pour balsamic vinegar mixture on top of meat.
  • Cook Close lid and seal steam valve on your Instant Pot or pressure cooker. Press meat/stew button and adjust cook time to read 1 hour 45 minutes total (or 22 minutes per pound you are using). When done allow to naturally release steam. Lift lid and slice or shred and then put meat back into pot with sauce to coat.
  • Thicken If you want a thicker sauce remove the pork and cover to keep warm. Set pot to saute and add 1/2 c of your hot liquid into a bowl + 2 tbsp of cornstarch. Whisk until smooth and add back into your pot. Stir and allow to bubble and thicken. Then turn pot off and put pressure cooked shredded pork back into the thick sauce, serve.
